Figure 5From: Improved elongation factor-1 alpha-based vectors for stable high-level expression of heterologous proteins in Chinese hamster ovary cellsDistribution of the eGFP expression levels in cell populations as determined by FACS analysis. Codes for the corresponding cell populations are the same as in Figure 3. First number after the cell population code: mean level of eGFP in the sample; second number: mean level of eGFP in the upper 10% of the eGFP-positive cells.Back to article page
